Problema Solution
If planet 1 is 31.3 million miles farther from the sun than Planet 2, then planet 3 is 23.6 million miles farther from the sun than planet 1. When the total of the distances for these three planets from the sun is 191.2 miles, how far away from the sun is planet 2
Answer provided by our tutors
let planet 2 is x miles farther
planet 1 is (x+31.3) miles farther
planet 3 is (x+31.3+23.6) miles farther
total diatance:
=> x +x +31.3+x+31.3+23.6 = 191.2
=> 3x + 86.2 = 191.2
=> 3x = 105
=> x = 35
planet 2 is 35 miles farther from sun.
